wat?

• Copy these lines into a Python REPL

# ---8<---
class Wat:
    @property
    def wat(self):
        print("\n...wat...\n...wat!?\n\n ?!?!\n\n")
        return 42

a = Wat()
# --->8---

• Now, type a., as if you were about to access some attribute of a. You should be seeing something like this:

>>> class Wat:
...     @property
...     def wat(self):
...             print("\n...wat...\n...wat!?\n\n ?!?!\n\n")
...             return 42
... 
>>> a = Wat()
>>> a.
